The research was not available as it was a new product back then. A year later, a few owner had problems with the pump and when the 2 year mark roll into, more owner of the mythical named pump from all around the world have problems with the pump.
What attract me to the pump was the low wattage and I sacrificed the funds to achieve that performance but I would have never dreamt that for the price I paid, the life span of the pump was similar to an infant. I would be happy if it reaches the 5 year mark but that will happen while the pump sits in the plastic bag under my bed. And the best part is for my case, my local Royal Exclusiv distributor told me the warranty was for 1 year only, not 2 like it was claimed by other here. How do you think I feel?
